Description

The invention relates to devices for transferring bulk materials mainly from zone to zone with different pressures and can be used to transfer aggressive and high-temperature materials from the chemical industry.

The aim of the invention is the expansion of technological capabilities by ensuring performance in an aggressive environment.

FIG. 1 shows schematically a sectional device; in fig. 2 - the same in the unloading cycle; in fig. 3 is a section A-A in FIG. 1; in fig. 4 — node I in FIG. one; in fig. 5 — node II in FIG. 2,

The device for reloading bulk material contains a lock chamber 1, inside of which the loading 2 and discharge 3 valves of vertical movement are located. Pneumopathy

The valves' waters are made in the form of bellows 4 and 5, tightly attached by one ends to the supporting platform 6, rigidly mounted in the sluice chamber 1, and the other ends - to the valves. Inside each bellows, to the platform 6, guides 7 and 8 are fixed, inside of which rods 9 and 10 are mounted with the possibility of axial movement, attached to valves 2.3. The valves 2 and 3 are connected to the platform 6 by means of return springs 11 and 12 through the earrings 13 and 14. The device is equipped with protective housings 15 and 16, the bellows 4 and 5 covering with a gap, the case 15 being fixed on the valve 2, and the case 16 - on the carrier platform 6. In the carrier platform 6, the channels a are also filled to communicate the bellows cavities with a source of compressed gas. The sleeves 17 and 18 of the bellows 4 and 5 are provided with throttling openings in the cavity that communicate the bellows cavities with gaps and protective enclosures 15 and 16.

The device is equipped with level gauges 19, docking flanges 20 and 21, and a pneumatic distributor of compressed gas 22.

The device works as follows.

The lock chamber 1 is filled with friable material with the loading 2 open and the discharge valve 3 closed. The bellows cavities are separated from the source of compressed gas by means of a pneumatic distributor. After filling the airlock chamber 1 with the material according to the signal from the sensor; the upper level 19, the pneumatic distribution valve 22 is activated and communicates via channel b

compressed gas through the channel The bellows is expanded, the discharge valve 3 is moved down, the discharge opening B is opened, and the material is discharged through the discharge opening from the lock chamber. At the same time, a part of the compressed gas is fed through the throttling holes in the gap between the bellows 5 and the protective housing 16, which prevents the bellows corrugations from being hit by material. At the end of the unloading, the signal from the low-level sensor 19 is supplied to the primary distributor 22, which separates the bellows cavities from the source of compressed gas and releases the gas in them first from the bellows 5 and then from the bellows 4. the valve closes and then the loading valve opens and the cycle repeats.

The device allows overloading of aggressive and high-temperature materials without damaging the pneumatic actuators.

Claims (2)

Claim 1, A device for transshipping bulk material, comprising a lock chamber, loading and unloading valves and pneumatic drives of vertical displacement valves with return springs, communicated with a source of compressed gas and installed with a gap inside the protective enclosures, characterized in that the purpose of expanding technological capabilities by providing performance in an aggressive environment, it is equipped with a carrier platform, rigidly mounted in a lock chamber, valve actuators are made in the form of bellows hermetically prikrep bellows cavity 4 th gas. Bellows 4 is mated together with the housing 15, and the valve 2 intersects the loading opening B to the lock chamber. Part of the compressed gas through the throttling hole in the sleeve 17 enters the gap between the bellows 4 and the housing 15 and pulls out of the gap loose material. After the charging valve 2 is closed, the pneumatic valve 22 communicates the cavity of the bellows 5 with the source the source is compressed with one end to the valves, and is extended, lifted by the other to the said supporting platform, while the bellows are made with throttling openings, the protective body of the unloading valve is fixed on the supporting platform, and the loading on the valve. 2. A device according to claim 1, characterized in that the pneumatic actuators of the valves are in communication with a source of compressed gas by means of channels made in the supporting platform. 55 . nineteen j: ffambiu Air dzig.2 /-/four Op rig 3 gz 7 .AT
